Answer:
B. outer
Step-by-step explanation:
The epidermis is the most superficial layer of skin, situated above the dermis, which acts as a protective barrier for the body. The word epidermis originates from the Greek terms Epi = over, outer, over, and Derma = leather, skin.
Waterproof, the epidermis makes it difficult for the body to get out of water and protects the body from external damage and the entry of substances and microbes into the body.
It is in the epidermis that are the melanocytes, the cells responsible for the production of melanin, the pigment that gives color to the skin. Skin attachments such as nails, hair, and sweat and sebaceous glands also originate from the epidermis.
